I've been casting about for a digital full-frame solution for my M lenses, and, for now, have decided to try a Kolari-modded A7 rather than spring for an M9. The thin filter seems to be working marvelously for legacy lens users, but I wonder if anyone has tried the CV 12mm Heliar? I can't seem to find anything in the usual places online. Thanks.
